NEET Physics Newton's Law of Cooling MCQ Question
Type: MCQ-numerical-Hard-Class 11
A hot object at temperature T_2 is placed in a large room with a constant temperature T_1. According to Newton's Law of Cooling, which of the following expressions represents the rate of cooling of the object?
A
-k(T_2 - T_1)
B
k(T_2 + T_1)
C
-kT_2
D
kT_1
Correct Answer
Option A
Detailed Explanation
Newton's Law of Cooling states that the rate of cooling is proportional to the excess temperature of the body over the surroundings, represented as -k(T_2 - T_1), where k is a positive constant.
